I don't think there is a definite "Lore" for heaven. Obviously there's a spirit realm (or several, for that matter). I believe many of those that follow "The Light" may believe in similar values of Catholicism, and believe in form of heaven. I think, on the average, the topic of actual specific 'religion' is avoided in most cases, and with good reason.

"Dead People" often end up in one of several places. Either their spirit remains on the physical plane (ghosts, spirits, wraiths, etc), they are on a slightly lower level (that you can only see while temporarily dead), or go to deeper levels that may only be accessible via magic or portals.

There is a place were the dead are at peace and can rest, don't know if it is heaven spirit realm or whatever. Sylvanas got there the first time she died, after Arthas death however she went to the void.

So the concepts seem to be there.

He who sees his own doom can better avoid its path. He who sees the doom of others can deliver it.

You cant prove something doesnt exist, only that it does. So until proven otherwise, his statement remains true. But we should rather be focussing on gamelore, otherwise this will get locked pretty quickly due to "religion bashing" and such..

<-- indicate pranking, fun, playful. Hence I hoped everybody would have seen it as a joke, sorry for not being clear about that

since you have prayers actually healing people, resurrecting dead people, spirit realm, ghosts etc, we can safely assume wow has 'working' higher powers and afterlife.
whether its a omnipresent force, probably not, since different beings die differently, and some like titans and old gods might not have working afterlife.
